Do SavingStar eCoupons stack with in-store discounts or manufacturer’s coupons?

SavingStar eCoupons will work whether or not you combine them with other services’ coupons, but they are not intended to be used this way. Generally, manufacturers state that it is against their policies for shoppers to redeem more than one manufacturer’s coupon for the same purchase. Using in-store coupons in combination with SavingStar eCoupons is not a problem.
